3 Claims.

This inventionrelates to stock quotation projection machines in general.

Among the objects of the present invention, it is aimed to provide an improved stock quotation projection machine in which the tape can with facility be fed across a light aperture or other support in a smooth and proper condition for projection by a device interposed between the ticker and the light aperture and without any m further controlling means.

It is still another object of the present invention to provide an improved mechanism for treating the tape whereby the same may be fed across a light aperture and the vibrations ironed out 15 of the same by one and the same device interposed between the ticker and the light aperture.

These and other features, capabilities and advantages of the invention will appear from the sub-joined detail description of specific embodiments thereof illustrated in the accompanying drawings in which:

Figure 1 is a front elevation partly broken away and partly in section of one embodiment of the present invention;

Fig. 2 is a fragmental plan partly in section of the embodiment illustrated in Fig. 1;

Fig. 3 is an enlarged fragmental section on the line 3-3 of Fig. 1;

Fig. 4 is an enlarged fragmental section on the 30 line 4-4 of Fig. 1; and

Fig. 5 is an enlarged fragmental section of a part of another embodiment.

In the embodiment shown in Fig. 1, the tape I as it leaves the ticker 2, preferably of the high ;5 speed type in which the normal feed has been disabled, is first engaged by the tape advancing roller 3 drivingly connected to the motor 4 by means including the belt 5, the tape I being pressed into driving engagement with the roller 40 3 by the pressure roller orspring pressed idler 6.

In the present instance, see Fig. 4, the tape advancing roller 3 has a creasing rib I cooperating with the groove 8 in the idler 6 to form an upwardly extending rib or crease 9 in the middle 5 of the tape I along the narrow extended area between the letters In constituting the stock symbols and the numbers H constituting the quoted prices. This creasing rib 9 will so stiffen or rigidify the tape I that it can with facility be engaged 50 between the ticker 2 and the light aperture now to be described not only to iron out the vibrations transmitted to the tape I by the ticker 2 but also effectively to advance the tape across the light aperture without any guiding means or advancing assistance.

In the present instance, however, there are provided the lateral guiding means such as the shoulders I2 and I3 formed by the top walls I4 and I5 of the extension I6 of the lamp housing II. The tape I here rides directly on the upper 5 plane supporting surface of the condensing lens I8 mounted in the extension I6 adjacent the upper walls I4 and I5 and adjacent the front wall I9. Preferably as here shown, there is secured a transparent sheet, such as the glass plate 20 to 10 the upper faces of the wall members I4 and I5 .so that this glass plate 20, cut condenser I8 and wall members I4 and I5 will cooperate to form a guiding pocket for the tape I whereby the tape will be guided in a smooth condition 'while cross- 16 ing the light aperture formed by the condenser l8 between the walls I4 and I5. As the tape I' after having been marked by the ticker 2, appears at the light aperture on the condenser I8, image impressed light beams are formed by the light 20 passing up through the condenser I8 and tape I, which light beams are intercepted by the objective lens unit in the casing 2| supported in position by the bracket 22 extending upwardly from the extension I6, which objective lens unit in turn directs the image impressed light beams onto the mirror or reflector 23 which directs them onto the mirror or reflector 24, which in turn directs them onto the rear of the projection screen 25 to be legible on the front of the screen 25.

Preferably as shown in Fig. 1, the screen 25 is provided with an opaque strip 26 to aline with the projection of the rib 9 so as to conceal the same when desired.

After leaving the condenser I8, the tape is 5 preferably passed to the extension 21 which extends into the cage 28 preferably composed of wire screening or other suitable foraminous material into which there extends in the embodi- -ment shown in Fig. 1, the jet or flame from the burner nozzle 29 communicating with the lower end of the cage 28 and extending upwardly from the oil burner 30 connected to the side of the extension I6. The extension 21, cage 28 and upper end of the nozzle 29 are preferably disposed in the casing 3| which is provided with air inlets 32 at the bottom thereof in the interest of combustion and a screened opening 33 at the upper end thereof in communication with the flue pipe 34 or the like.

With this burner arrangement, it is not necessary to use a rewind of any kind and the tape as it has served its usefulness is destroyed, the front feed and rib- 9 of course cooperating with the burner to dispense with a rewind of any kind.

In the embodiment of Fig. 1, the cage 28 is preferably cylindrical as shown in Fig. 2 and anchored in place by the spring fingers 44 extending from the side of the extension l6. Furthermore the housing 3i is preferably provided with a hinged closure 45 which may be opened to afford access to the cage 28.

The cage 46 of the embodiment illustrated in Fig. 5 preferably is also anchored in place by spring fingers, such as the spring fingers 44 of Fig. l, and the door 41 there provided is also provided to. afford access to the cage 46.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I claim:

1. The combination of a ticker, an inspection area having a plane supporting surface, means interposed between said ticker and said inspection area for advancing the tape from said ticker to and across the supporting surface of said inspection area, said advancing means including a driven roller and a pressure roller for maintaining the tape in driving engagement with said driven roller, and cooperating rib forming die faces on said driven and pressurenrollers for forming a longitudinally extending stiil'ening rib in the tape to facilitate the steady advancement of the tape across said inspection area in intimate engagement with said supporting surface.

2. The combination of a ticker, an inspection area having a plane supporting surface, means interposed between said ticker and said inspection area for advancing the tape from said ticker 10- to and across the supporting surface of said inspection area, said advancing means including a driven roller and a pressure roller for maintaining the tape in driving engagement with said driven roller, an annular rib forming pro- 18 jection on said driven roller, and an annular depression in said pressure roller registering with said projection on said driven roller forforming a longitudinally extending stiffening rib in the tape to facilitate the steady advancement of the I) tape across said inspection area inintimate en-' gagement with said supporting surface.

3. The combination of a ticker, alight aperture pocket formed by the plane surface of a condensing lens, a glass plate above said condens- :8 ing lens, and lateral walls on the side, means interposed between said ticker and said pocket for advancing a tape from said ticker to and through said pocket, and means for forming a longitudinally extending rib in the tape for stiiI- 80 ening it to facilitate its movement through said pocket in intimate engagement with said plane surface, the width of the pocket conformin the width of the tape and the height of the pocket conforming to the height of the rib on 86 the tape.
